Special Regulations & Warnings
Although summer air temperatures are pleasant, sand temperatures can soar to 140°F (60°C), so park officials strongly advise that shoes be worn when hiking in the dunes. Also, summer thunderstorms are fairly common. Hikers are advised to leave the dunes quickly when lightning threatens, to avoid the chance of being struck.
Elevations range from 7,515 feet to 13,604 feet, so those from low elevations are warned that they should take it easy until they have adapted and drink plenty of water to avoid altitude sickness, which causes shortness of breath, headaches, and nausea.
Pets are permitted throughout the park and preserve but must be leashed, and officials ask that owners clean up after their pets. They also warn that the sand in the dunes can be hot and will burn the pads on dogs' feet, so they suggest dune hiking with pets early or late in the day, when the sand is cooler.
